Actually, its broader than a piercing weapon. The hand guard may give it an illusion that is is though.

As for the main design, it was based off of Lufia II's artwork. I remixed the guard for more detail and protection.

Realistically, even long swords aren't that thick (you might be thinking broadsword or a typical rpg). Still, I wanted to craft Dual Blade as superior to all medieval weapons at the time (don't let FF fool you with their weapons).

Its blade is more reminiscent of a Katana (it needs to be longer, but I ran out of room in my sketchbook) which is faster and lighter than a medieval longsword while more durable than a rapier (meaning it can cut armor instead of just stabbing). The handle has enough space for two hands.

Nevertheless, the sword is versatile for one or both hands and is flexible with many sword styles.
